Question 2x4 pin to 6 pin or 1x4 pin to 6 pin ?

Recommended Posts

Posted · Original PosterOP

Im using a Msi gtx 970 which requires 2x6 pin connectors.
And my power supply has 1x6 pin.
And i have like 3x4 pin left unused.
So can i use that 4 pin to 6 pin converter ?
Im confused between these two....

2)https://www.amazon.in/Invento-Molex-Express-Adapter-Y-Cable/dp/B07J44FFQZ?tag=googinhydr18418-21 
Whats the difference between these two ?
Which one should i use ???

More connectors = better for higher current.

But I doubt that a single GTX970 would melt a MOLEX 4 pin so: it does not make a difference for you

Generally you shoud no use adaptors like these, because they can burn out quiet easy. However the second one is saver if you use two different cords of the psu.

Use the one with 2 molex (hdd) connectors

 

A 6pin pci-e connector is supposed to deliver up to 75w to the video card through 2 or 3 pairs of wires (12v and ground)

 

A single molex (hdd) connector has a pair of 12v and ground, but the connector is designed to safely carry up to 5A of current (approximately 60 watts)

 

So, it's safer overall to use an adapter which takes power from TWO molex connectors, this way those 75w are split between two hard drive connectors, so each connector only transfers about half of that 75w number, let's say 40w... that's well below the 60w maximum safe limit of the molex connector, so it's better.
